Description

The present invention relates to a dye-containing negative curable composition suitable for forming a colored image constituting a color filter used in a liquid crystal display device (LCD), a solid-state image pickup device (CCD, CMOS, etc.), and the dye-containing negative. The present invention relates to a color filter using a mold curable composition and a method for producing the same.

As a method for producing a color filter used for a liquid crystal display element or a solid-state image sensor, a dyeing method, a printing method, an electrodeposition method, and a pigment dispersion method are known.

Among these, the pigment dispersion method is a method for producing a color filter by a photolithography method using a colored radiation-sensitive composition in which a pigment is dispersed in various photosensitive compositions. It has the advantage of being stable to heat and the like. Further, since patterning is performed by a photolithography method, it has been widely used as a suitable method for manufacturing a color filter for a large-screen, high-definition color display with high positional accuracy.

When producing a color filter by a pigment dispersion method, a radiation sensitive composition is applied on a glass substrate by a spin coater or a roll coater and dried to form a coating film, and the coating film is subjected to pattern exposure and development. Colored pixels are formed, and a color filter can be obtained by repeating this operation for each color.

As the above pigment dispersion method, there is a method in which a negative photosensitive composition in which a photopolymerizable monomer and a photopolymerization initiator are used in combination with an alkali-soluble resin is described (for example, see Patent Document 1).

On the other hand, in recent years, there has been a demand for higher definition in color filters for solid-state image sensors. However, it is difficult to further improve the resolution with conventional pigment dispersion systems, and there are problems such as color unevenness caused by coarse particles of the pigment, so that it is used for applications that require fine patterns such as solid-state imaging devices. Was not suitable.

In view of such a problem, a technique for using a dye instead of a pigment has been conventionally proposed (for example, see Patent Document 2). However, dye-containing curable compositions generally have a problem that light resistance is inferior to pigments. Furthermore, unlike in the case of semiconductor manufacturing applications, a film thickness of 1.5 μm or less is required especially in the case of color filter manufacturing applications for solid-state imaging devices, so a relatively large amount of dye is contained in the curable composition. As a result, the adhesion to the substrate (support) becomes insufficient, and there is a problem that the film is easily peeled off by the development process.

In addition, there has been disclosed an example of adding an amine compound in a color filter using a pigment (see, for example, Patent Document 3). However, when a fine pattern having a side of 2.0 μm or less is formed, color unevenness occurs, and when such a fine pattern is formed, there is a problem that the peeling control by development is insufficient. In addition, an example in which a hindered amine compound is added to a color filter using a staining method has been reported (for example, see Patent Document 4). This example also has a problem that the adhesion to the substrate is insufficient. Note that some positive photosensitive resin compositions may improve storage stability by adding an amine compound or a pyridine compound (see, for example, Patent Document 5).
JP-A-2-199403 JP-A-6-75375 JP 2000-98124 A JP-A-62-102201 JP 2002-196482 A

However, the negative curable composition containing a dye has good light resistance that hardly causes discoloration of the formed image, and can be made into a thin film and a high concentration while using the dye as a coloring material. It can be said that the technology that can sufficiently secure the adhesion to the substrate (support) even when the substrate is formed has not yet been established.

This invention is made | formed in view of the above, and makes it a subject to achieve the following objective. That is, an object of the present invention is to provide a dye-containing negative curable composition having high light resistance and having good adhesion to a support even when a fine pattern is formed.

Among the above amine compounds, tertiary amine compounds, tertiary aniline compounds, or hydrazine compounds are preferable in that the effects of the present invention can be effectively achieved.

When determining the oxidation potential, first, sweeping is started so as to increase the potential to the plus side (example: ± 0 V → + 2.0 V). Then, the oxidation wave is measured when oxidation occurs. Usually, the results of the oxidation and reduction potential measurement are plotted with the horizontal axis representing the potential and the vertical axis representing the amount of current flowing between the electrodes. That is, the oxidation wave means a waveform having a peak (vertex) that swings above the base line indicating a state in which no current flows. This waveform is expressed as a half wave of the oxidation potential, and the peak (vertex) potential of the waveform is expressed as E _pa . E _pa in the present invention is a value measured by the following method.

Using a measuring instrument connected to an arbitrary function generator, potentiostat, and measuring vessel, 0.1M n-Bu ₄ N · ClO ₄ (for Hanai Polaro) is measured as a supporting electrolyte in the measuring vessel. It was dissolved in acetonitrile (manufactured by Kanto Chemical) as a solvent and used. The electrode used was a Pt electrode as the working electrode and Ag / AgCl (saturated KCl) as the reference electrode. As the salt bridge connecting the reference electrode and the measurement container, agar containing 1 M KNO ₃ supporting salt was filled and used. Under the above conditions, the sample was dissolved in a measurement container so as to be 1 × 10 ⁻⁴ M, and measured at a sweep rate of 50 mV / cm ² to 1 V / cm ² at 25 ° C.

Next, using an i-line reduction projection exposure apparatus, the coating film was irradiated at a wavelength of 365 nm through a mask having a light transmission portion of 2 μm square with an exposure amount of 800 mJ / cm ² . After irradiation, development was performed at 23 ° C. for 60 seconds using a 60% CD-2000 (Fuji Film Arch Co., Ltd.) developer. Subsequently, after rinsing with running water for 20 seconds, spray drying was performed to obtain a yellow pattern image.
